A former midwife who was at homebirths where four babies died has decided not to attend or challenge disciplinary proceedings.

The Nursing and Midwifery Board in South Australia has accused Lisa Barrett of professional misconduct, saying she planned and was involved in homebirths in unsafe circumstances.

In January 2011, she surrendered her midwifery registration but the Health Practitioners Tribunal was told there was evidence she had kept working in the homebirth area.

The board wants her permanently banned from providing birth services.

Ms Barrett did not attend the tribunal hearing in Adelaide.

She sent a note, which was read to the hearing: "To save the parties time and expense, I've decided not to participate in the proceedings".

The Nursing Board told the hearing Ms Barrett had planned to give a homebirth and midwifery seminar in Las Vegas next month.

Industrial Magistrate Michael Ardlie said there was no doubt Ms Barrett's actions had amounted to professional misconduct.

He said the tribunal was dismayed her behaviour had continued unabated since the deaths.

The Community Complaints Commissioner issued an order last month banning Ms Barrett from providing birthing services.

The tribunal was told it should impose a similar order.

It was told Ms Barrett can appeal against the Commissioner's order within 30 days and having a separate prohibition order would protect the public and send a message to practitioners about acceptable standards.
